  • This construction of a pneum-atic tube is particularly suitable for rabbit operation in a nuclear reactor.v
  • One of the conduits leading from the departure side of the station to the arrival zone in the reactor serves for the back ⁇ and for-th run o'f the rabbit and the other for supplying and removing the pressure gas.
  • side of the station one of the connections serves for sluicing-in and carrying out the rabbit and another for supplying and removing the pressure gas.
  • the outlet conduit -for the cont-aimer on the loading side and the transport conduit for the container at the departure side of the station on the one hand, and the outlet conduit for the pressure gas at the loading side and the pressure and outlet gas conduit on the departure side of the station on the other hand are oppositely disposed and iixedly aligned with a space therebetween; in that the sluicing-in conduit for the container and the inlet conduit for the pressure gas at the loading side are spacially offset to the same degree with respect to t'he corresponding coordina-ted container outlet and pressure gas outlet conduits; and in that in the space between the loading and departure side of the station are serially inserted, and sealed against each other two displaceable conduit joints with conduits aligned and in register with the conduits of the corresponding connecting sides of the station, the joint located at the loading side being provided, instead of and in the same position as a container outlet conduit, with pockets communi-cable
  • the conduit joints are preferably formed as rotatable cylinders and the loading and departure sides of the station as fixed plates.
  • the plates are centrally connected lby a shaft on which are mounted the cylinders which are rotatable in the same or 4in opposite direction and have their faces in sealing engagement.
  • the conduits of the station and their external connections are distributed over arcs of circles which all lie in register about the axis of rotation.
  • One of the conduit joints constitutes the control element.
  • the other serves as loading and shooting-out chamber.
  • the latter has conduits of at least the same length of a pneumatic tube container, while the control cylinder is formed as a disc.
  • the control element controls primarily the pressure medium and secondarily the connection of the transport conduits.
  • FIG. 1 is a perspective exploded view of the loading and control station
  • FIGS. 2a and 2b are a section and a front view respectively of the station, as seen from the loading side in rest position;
  • FIGS. 3a and 3b are views corresponding to FIGS. 2a and 2b respectively, showing the sluicing-in position
  • FIGS. 4a and 4b are views corresponding to FIGS. 2a and 2b respectively, showing the shooting-out position.
  • the loading and control station has on the loading side a sluicing-in conduit Er and an outlet conduit Ar for the carrier containers, and one inlet and one outlet conduit Ed, Ad for the pressure gas.
  • the station serves two pneumatic t-ube systems the connections of which lie on either side of the division linel L.
  • At the departure side of the station are correspondingly provided two transport conduit Kt for the containers and two pressure and outlet gas conduits Kd. All the conduits lead to the point of arrival in the reactor.
  • the gas pressure conduits are connected to the transport conduits for the purpose of returning the pressure gas.
  • the front side of the station is the loading side. It is here that the container (rabbit) is sluiced into the tube system.
  • the departure side is disposed at the rear in the drawings.
  • FIG. l clearly illustrates the characteristics of the invention, which are described hereinafter with reference to one of the two conduit systems.
  • outlet conduit Ar for the container at the loading side and the transport conduit Kt of the container at the departure side of the station on the one hand, and the outlet conduit Ad for the pressure gas at the loading side and the pressure or outlet gas conduit Kd at the departure side of the station on the other hand, are oppositely disposed and fixedly aligned with a space therebetween.
  • the sluicing-in conduit Er for the container and the inlet conduit Ed for the pressure g-as at the loading side are spacially offset to the same degree with respect to the corresponding (coordinated) container outlet and pressure gas outlet conduits Ar and Ad.
  • pockets T which can communicate with the container transport conduits Arz of the joint Vll disposed at the departure side, but cannot communicate with the container transport conduits Ar at the loading side.
  • the pockets in the loading-side joint create a lateral turn of the pressure gas inlet conduits AE. These are widened in the direction towards the sluicing-in conduits Er into longitudinal slots of the shape and volume of longitudinal openings formed by unifying two coordinated conduits (Ar, Er or Ed, Ad).
  • conduit joints Vl and Vll are in the form of rotatable cylinders and the loading and departure side of the station are in the form of fixed plates Fl and Fll.
  • the cylinders are mounted between the plates with all their faces in sealing contact and are rotatable in the same or in opposite direction about a central shaft W.
  • conduit connections and conduits of Ithe station lie on registering arcs of circles about the axis of rotation of the cylinders.
  • the conduits Ar2 and Adz of the cylinder Vll which forms the loading chamber are at least as long as a rabbit.
  • the control element Vl may be made substantially shorter, in the form of a disc.
  • the station is formed in regard to the conduits which are present as a twin station, with the conduits of like function being oppositely disposed with respect to the axis of rotation W.
  • the conduits of like function being oppositely disposed with respect to the axis of rotation W.
  • FIGS. 2r: to 4b show in general that the plates Fl and Fll are connected at the corners by threaded bolts B, which also function as spacers, ⁇ and by screws F.
  • the rotation shaft of the conduit joints is tubular and penetrates into the plates.
  • the conduit joints Vl and Vll themselves are freely mounted on the shaft. They are connected to drives Kl and Kll respectively through the intermediary Of lll'lkS MI and MII.
  • the loading chamber Vll is rotated in clockwise direction through 30 (FIGS. 3a and 3b). Thereupon .the conduits Er, Erl and Arz of the plate, control disc and loading charnber respectively, are in alignment and the rabbit may be pushed into the loading chamber Vll. By turning the loading chamber back -to its original position the rabbit cornes to lie in front of the pocket T and at the same time in line with the transport conduit Kt.
  • the longitudinal opening AE of the control cylinder communicates with the pressure gas inlet conduit Ed of the plate Fl.
  • conduit Ed gas By opening of a valve (not shown) in .the gas supply pipe to conduit Ed gas enters behind the rabbit and drives it to its goal.
  • the spent gas exits through the conduit connection Kd, Adz, Adl and Ad.
  • Conduit Ad is connected to the spent gas system of the pneumatic tube.
  • the rabbit is received at the point of arrival and remains there until it is shot back.
  • the shooting-out operation is set ott from the loading and control station.
  • the control cylinder Vl is turned in counterclockwise direction through 30 (FIGS. 4a and 4b). In this position the conduits Kt, Ar2 and Erl are aligned and in register.
  • the rabbit thus has available a transport condui-t leading to the outside of the station.
  • the pocket T of the control cylinder is inoperative but its longitudinal opening places into communication the pressure gas inlet and outlet conduits Ed and Ad of the plate Fl. If the valve in the gas supply pipe to the conduit Ed is again operated, pressure gas passes from conduit Ed through AE into conduit Ada and from there through Kd and the connecting pipe it reaches behind the rabbit. Of course the outlet pipe leading from conduit Ad to the exterior is closed.
  • the rabbit is set in motion and leaves the station through Ar pushing lthe spent gas ahead of it.
